Pacman error - libdav1d.so.4()(64bit) needed by libavcodec58

**HarryL** · 27-Nov-2020, 08:37

Hi Guys.. need some more of your time and help and it is not to be confused with this problem found at this link;
https://forums.opensuse.org/showthre...des-libhogweed
which I posted several days ago.

That problem was related to libhogweed.so.5 and resolved at this link;
https://forums.opensuse.org/showthre...646d-1-53-x86_

But despite everybody's great efforts this problem is new and gives the following output when I use;
# sudo zypper dist-upgrade --from packman --allow-vendor-change

Computing distribution upgrade...

Solution 1: deinstallation of gstreamer-plugins-libav-1.18.1-1.1.x86_64
Solution 2: keep obsolete gstreamer-plugins-libav-1.18.1-1.1.x86_64
Solution 3: break libavcodec58_91-4.3.1-8.3.x86_64 by ignoring some of its dependencies

Any help is appreciated in advance - Regards Harry

First, I'll comment on the thread title. As far as I know, "pacman" is the package manager for the arch distro. You probably meant "packman".

Second - what to do? If it were my system, I would go with solution 2 -- and hope that the problem clears up at the next update.

For myself -- I did not see any problems with this update. But, after updating, I checked for orphaned packages. And a couple of packages showed up as orphaned. When I tried to remove those orphaned packages, I got similar conflicts to what you are seeing. So I left the orphaned packages there for now.

Cleaning up the new orphan has some side effects:

That's why I usually go to Yast to remove orphans. At least Yast warns me about the other removals, while zypper seems happy to just go ahead and cripple my system.

In my opinion Tumbleweed users should try 'zypper dist-upgrade --dry-run' and report any problems at packman <at> links2linux.de http://wiki.links2linux.de/packman:f...with_a_package Most problems are trivial and the folks at packman fix them really fast if they are aware of them.
